63. In cancer cells one allele of the tumor suppressor gene p53 is frequently mutated so that the protein is inactive, not produced, or deleted. The other allele will usually … promoter remains intact but the gene is not expressed. Sequencing with sodium bisulfite modification of DNA can be used to detect which cytosines are methylated. …what would be the anticipated results? Cytosines in or near the promoter region will be methylated Cytosines in or near the promoter will not...

You insert a gene for tetracycline resistance into one plasmid and a gene for ampicillin resistance into another plasmid. You successfully introduce both plasmids into a sample of E. coli cells, but fail to grow any of them in culture medium with both antibiotics present in it. What could best explain the problem? A. Random mutation has inactivated the antibiotic resistance genes B. Plasmid incompatibility will not allow both plasmids to persist C. E. coli cannot maintain two plasmids D....
